| Abstract |
This paper presents an experimental evaluation between Direct Torque Control (DTC) and Finite Control State Predictive
Torque Control (FCS-PTC) applied to induction machines. Both control strategies have features in common: absence of a modulator, fast dynamics. Regarding the conceptual understanding and system constraints the PTC method shows advantages compared to the DTC method. However, compared to PTC, DTC method has lower calculation time. An experimental comparison is carried out in this work. The same average switching frequencies at specific operating points for two control methods are taken into account in order to reach a fair comparison. The experiments confirm that both PTC and DTC methods reach good results and achieve very comparable performance both in steady and transient states. |
